Thread-topic: [HVM][XENOPROFILE][PATCH][2/3] xenoprofile HVM patches
second patch (SVM) for hvm xenoprofile support. 
Applies cleanly to 11470.

Signed-off-by: Tom Woller <thomas.woller@xxxxxxx>
Please apply to xen-unstable.hg.

hvm_xenoprofile_2.patch -
The second patch adds the actual xenoprofile fixes for SVM:

1) hvm function (svm_oprofile_get_eip())
This new hvm table function is called from the op_module_athlon.c code,
and returns the proper eip and "mode" for use in the
xenoprof_log_event() function.  

2) The vmexit handler code now checks the exitcode and if an NMI was
intercepted, then prior to the stgi(), a flag (VGCF_hvm_guest_nmi) is
set in the v->arch.guest_context.flags field.   The VGCF_hvm_guest_nmi
bit is checked during NMI processing via the hvm function callback.
